In diabetes, you can take 5 to 10 goji berries when your blood sugar is under stable control. In Chinese medicine, wolfberries are believed to nourish the liver, improve eyesight, and enhance immunity, but they are not exactly helpful for blood sugar management and control. Simply as a health supplement, when blood sugar control is stable, you can take about 10 grams of wolfberries, or about 5 to 10 capsules. If in some cases, the Chinese medicine doctor diagnosis suggests the need to take Chinese medicine containing wolfberries, then it should be taken according to the prescription of the Chinese medicine doctor. It should be noted that wolfberries have a high sugar content and may have an effect on blood sugar. If there is any discomfort, consult a doctor promptly.
